This thread is similar to the thread at How-To: Bypass Kemco Anti-Tamper & License Check.
You can follow that guide but with a slightly different option at the end. That is why this thread was created.

Remember, This method is only for APKs that have been modified using Lucky Patcher.

Choose a Kemco game of your choice. In my example, I used a game titled Infinite Dunamis from this thread at
{Kemco} RPG Infinite Dunamis Paid .apk "
You can check the problem in the comment section, but you don’t have to since you’re probably facing the same problem anyway.

As you can see, like other shared patched APKs, its signature uses the testkey. Our goal is to disable or delete this key.
Open Lucky Patcher , select the APK, and then choose "Rebuild."

After that, choose the option
"Re-sign with original signature for the android patch "Disable .apk Signature Verification."

Then, choose "Select application file to copy signature." and select an apk file.

In my example, I am using this APK titled Journey To Kreisia, a paid APK, from this thread

I am using this because it is an untouched APK with the original signature, and it’s from the same publisher.

FYI: I have been using only this APK to re-patch all Kemco games that I downloaded from this forum which have issues with Anti-Tamper Protection and IAP problems.

However, you can choose another APK from the same publisher or even an APK outside of Kemco, which I have not tested yet, but you can try your luck. The important thing is to download the smallest APK size for convenience.

Remember to use only the untouched/unmodified APK file for this process.

Select the APK and then click "Yes."

Next, click the re-sign button

After it’s done, the file will be named with the extension orig_resigned.apk.

This will result in the signature being disabled or deleted.

At this stage, since the APK no longer has a signature, it cannot be installed.

However, this means the APK now behaves like an untouched or unmodified APK file.

Next, re-patch the APK using Lucky Patcher to bypass the Anti-Tamper protection and enable the In-App Purchase (IAP) function. If you are not familiar with the patching process, you can simply follow the images below for guidance.

5. Wait until it finished.

Finally, after the process is finished, the file name should look something like this.

That's it! 🙂

I want to try this, however, the issue I am having is locating an older Kemco game unlatched.
Is it possible to import a signature using a different Kemco game just for the purpose of removing it?

Yes, it is possible. I’ve already tested it. The APK I recommend is just for convenience, since Kemco games have been getting larger lately, so it’s better to download the smaller one..

you also can try to resign the modified apk with an orginal installed

mod the apk
install the orginal
open the modded apk with Lucky Patcher while the orginal is installed and resign it with the rebuild option from the orginal

works on several like .. youcut polish ...

... as i wrote you can rebuild and resign while the orginal is installed and take the info from it _nobody talk about install at same time without cloning
if you processed the rebuild - the orginal can be uninstalled - why we talk about basics

you need a rooted device for some things to handle ... or most thing in modding if y wanna work flawless with things
